Manny Pacquiao's wife Jinkee says the Pac-Man is too wiped out after fights to go another round in the bedroom -- but karaoke? Well, that's a whole other story.

As most of you know, some boxers and trainers believe it is best to avoid having sex before a fight. The timezone in which they refuse to do the dirty varies from person to person and some boxers don't believe in it. I believe Oscar De La Hoya was one of the fighters who didn't believe in that theory.

Do you think no sex before a fight has any merit? What about jerking it? Do you know if any other fighters believe in the theory that it's bad?
